M yfinvention relates to mechanisms for supplying fastenings 4to the mechanism which iswto transfer' them to the point of utilization. Theinvention is lherein illus- 5 trated as' applied toanail-"distributor delivering to the loading :mechanism of a heel-attaching machine. f In 'nail-distributors ofheeling machines, it is a common'practice to "startthe mecha# 10 nismiin operation for nail-'delivery when the loader-block, in wlriich"A the nails are to be transferredcto the dielblockvof, the heeler, reaches -afreceivingv position. A distributing mechanism organized toact in this Vmanner is made'the subject' off United States Letters Patent No. 1,005,303', granted 'October`10,

1911,' on application of JosephI-I. Pope. In

this,a clutch, released upon the arrival of the loader-block beneath the 'foot-plate in which 'the nail-delivering'tubes terminate,

acts througha chain of elements, includingy gearing, a clutch, cam, lever, connectingfrod and crank, to impart tothe dischargeroll of the distributor its movement .by which it delivers nails received directly from the movable raceways upon whichthey are? supported in series end toend. It is sometimes found that a highly efficient operator is so rapidk in his movements that he will have` a shoe heeled, removed from the jack and another shoe and'heel ready for nailing before a load of nails can be delivered from the distributor and transferred to the die-y block ready for driving. There may consequently be forced upon him a series of in prompt supply of nails to the transferring mechanism. This I accomplish byv transmitting movement to the discharge device from the loading or transferring mechanism, thus avoiding the necessity for control of an external source of power and the application brenne p of. this power, with the onsequent delay. -By causing the loading mechanism to act'di- .rectly upon the discharge device, the'latter is started into` action coincidently with the arrival of the loader-blockat the receiving position. the lspecifilcform of my inven- -tionherein -dis'clos`ed,nsuch a member asa rod vispmoved vertically by the loader-arm, and hasy a. constantly effective" connection Ito the discharge-*roll 'A of the'f distributor, v by which connection' the'4 rectilinear movement of the member` is transformed intofoscillationfat the roll. l f 'The accompanying drawing shows oneof the several embodiments which this inventionsmayl have. y c 7, f..

Having described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:
